在生產過程中，當樣本自然散佈的範圍遠小於規格上下界限時，抽樣樣本平均值被允許_在一定的範圍中變動，此時，品質管制的目的在於監控所生產的產品是否符合規格，而非監控製程狀態，在這種情形下，使用允收管制圖是較為合適的。如果以允收管制圖為基礎，並使用變動抽樣樣本大小的手法，當可降低抽樣樣本數。然而，當製程因工具磨損導致製程偏移加速時，若使用固定的抽樣間隔來監控製程，可能會降低該管制圖的監控靈敏度，所以，本研究以調適性允收管制圖為基礎，導入變動抽樣間隔而建構出新的調適性允收管制圖-變動抽樣間隔，並證明可藉由變動抽樣間隔的手法來提升調適性允收管制圖的監控靈敏度。

As the natural dispersion of a process is much less than the specified tolerance, there is acceptable for the process mean to shift within the lower and upper specification limits. When quality control is aimed at monitoring whether or not the produced out of the specification, not monitoring the process, then using acceptance control chart is more desirable. Nevertheless, when the process mean shifts quickly that is related to tool wear, it may reduce the sensitivity of acceptance control chart by using a fixed sampling interval. In this study, we use variable sampling interval to build a Variable Sampling Interval - Adaptive Acceptance Control Chart based on adaptive acceptance control chart. We improved the sensitively of the adaptive acceptance control chart by using variable sampling interval.
